These devices prevent fuel from draining or siphoning out of the tanks inappropriately.\n\n**Deadline:** Complete the inspection within 100 flight hours after 31 July 1983, unless already done.\n\n**Why it matters:** Incorrect anti-siphon assemblies could allow fuel to leak or drain improperly, creating fire risks or potential fuel starvation during flight.
